Recently, many places across the country have continued to experience high temperatures. Many people may not know that continued high temperatures may also cause your computer system to quietly slow down. If the computer itself does not dissipate heat well, it may even cause it to crash. Therefore, in order to allow the computer to dissipate heat better and survive the summer smoothly, it is very necessary to thoroughly remove dust from the inside of the computer. And regular dust removal can effectively reduce damage to the computer. Next, the editor will introduce to you the steps to remove dust from Lenovo y460 notebook.

1. Tools, raw materials and preparation work

The preparation work that needs to be done before starting to clean the dust is relatively simple but also very important. First, you need to prepare the relevant tools needed to disassemble the machine. Well, screwdriver, silicone grease, air blower, flannel, toilet paper, etc. It is also best to prepare a pair of anti-static gloves to prevent static electricity from breaking down memory and other parts. However, you can also touch a metal object first to discharge static electricity from the body. It is recommended to choose an environment that is not too dry for disassembly and cleaning. On the one hand, it can prevent dust from flying around, and on the other hand, it can also prevent the generation of static electricity to the greatest extent.

2. Methods and steps

Disassembly and cleaning of dust

After the above items are ready, you can start to disassemble and clean the dust. Lenovo Y460 is a machine with a relatively open cooling system design. Users only need to open the cooling window in the upper right corner of the bottom of the machine to clean the entire cooling system. Be sure to disconnect the power supply before disassembling the device, and if possible, remove the battery.

After opening the cooling window, you can see the dust-filled cooling fan. Judging from the dust, it is necessary to clean this machine. . There is also some dust attached to the disassembled heat dissipation window. Although the dust on these surfaces does not have a great impact on the overall heat dissipation, it is still necessary to clean it now that it has been disassembled.

We can see that there is some dust attached to the memory. Use a brush to gently sweep it clean. What you need to pay attention to here is to ensure that there is no static electricity on your hands. Although the probability is extremely low, static electricity may still damage the memory, so it is better to be cautious, especially when the memory price is high now, it is not cost-effective to buy memory.

After unscrewing the screws that fix the CPU, graphics card and fan, you can slowly remove the heat-dissipating copper tube and pass through the old silicon attached to the copper tube. Grease, we can infer that too much silicone grease was applied to this machine when it was last cleaned. Too much silicone grease is not a good thing for the cooling system.

In addition, there is a lot of dust attached to the scales of the air outlet. A large part of the reason why the heat cannot be discharged smoothly is because there is too much dust here to hinder it. Movement of hot air.

Use toilet paper to slowly clean up the old silicone grease attached to the heat-dissipating copper tube, and use air blowers or other tools to remove the dust attached to the heat-dissipating scales. You can also consider flushing it with water, but Pay attention to drying as soon as possible.

When taking off the cooling fan, pay attention to the connection cable between the fan and the motherboard. After slowly disconnecting the cable, take off the fan and use an air blower, toilet paper, etc. Start cleaning. It is not recommended to disassemble the fan blades.

Clean the surface of the motherboard

Finally, let’s look at the attachments on the motherboard. In addition to the silicone grease on the CPU and graphics card, there is a lot of dust everywhere on the motherboard, especially around the components on the graphics card and below the CPU. There are many flocs. In order to allow better heat dissipation of the graphics card chip, this machine is also equipped with a copper plate.

Use toilet paper, brush, etc. to slowly clean up all these dirty things. Be careful not to be too rough when wiping the silicone grease on the surface of the CPU and graphics card. There is a lot of silicone grease embedded in the grooves around the chip. Just wipe it off if you can. Don't worry too much about wiping it off. If you accidentally damage the chip, there is really no way to recover it. Just clean the silicone grease above the chip.

Apply silicone grease

The next step is the process of applying silicone grease. The function of silicone grease is to speed up the process of heat conduction from the chip to the heat dissipation copper sheet, so the thinner the silicone grease, the thinner it is. The more uniform the effect, the better. This machine clearly had too much silicone grease applied last time. Apply a small amount of silicone grease evenly on the top of the graphics card chip. Since it also has a heat dissipation copper sheet, you need to apply a layer above the graphics card chip and a layer above the heat dissipation copper sheet.

Installation process

After everything is done, put the heat dissipation copper pipe, fan and memory back in sequence. Be careful not to forget to Connect the cable connecting the fan to the motherboard. Finally, put the cooling window back, put in the battery and turn it on to see if there are any flaws. The disassembly and assembly of this machine is relatively simple, so even if there is a problem, it is not very troublesome to reopen the heat dissipation window. If it has an integrated back cover, it is recommended to turn on the power first, and then tighten the screws after confirming that everything is normal. This is much more convenient than disassembling the machine after discovering a problem. After confirming that everything is normal, wipe the screen and body with screen cleaning fluid and a soft cloth, and you're done. Although it can't make it look like new, it can definitely make it look better.Clean and more comfortable to use.

Above, the editor has given you a detailed introduction to the steps and some tips for dust removal on Lenovo y460. I believe you will have a certain understanding after reading it. Lenovo y460 notebook is a notebook with a very open design in the cooling system, so it is not difficult to disassemble and remove dust by yourself. As long as you pay attention to some small details, you can do a good job of dust removal. Friends who have strong operational skills, are careful and bold, and have experience in computer maintenance can try to remove dust by themselves. Novice users are advised not to clean up by themselves as much as possible.
